"mille" still isn't type-correct

[Guy Harris]

Index:	games/mille/mille.c games/mille/move.c 4.3BSD

Description:
	"NULL" is defined as 0, which is an integral type.  The
	second argument to "setbuf" should be of type "char *".
	Thus, "NULL" by itself is not the correct argument to
	"setbuf".
Repeat-By:
	Try "lint"ing "mille".  If it passes, either your "lint" is
	wrong (some S5 versions allow that sort of bullshit, but
	they shouldn't) or your definition of NULL is wrong (it
	should NOT be defined as "(char *)0", since that causes
	problems if you want to pass a null pointer of another type).
Fix:
